Imagine a colossal loop city stretching across Britain and Ireland, seamlessly connecting nine major cities through a high-speed rail network. Sounds like something out of a sci-fi novel, right? But this isn’t fiction—it’s a bold proposal from RIBA President Chris Williamson, and it’s sparking both awe and debate. Inspired by Saudi Arabia’s audacious 170km-long Line project, Williamson’s vision aims to transform the north of England, Scotland, Wales, and Ireland into a ‘new global city, dispersed but connected.’ Here’s the kicker: this isn’t just about trains. It’s about reimagining how we live, work, and collaborate across borders.
The Northern Powerhouse Loop would link Dublin, Belfast, Glasgow, Edinburgh, Newcastle, Leeds, Manchester, Liverpool, and Bangor via 50-meter-long trains zipping along at up to 300 miles per hour. And this is the part most people miss: these trains would run on an elevated viaduct, minimizing ground-level disruption while maximizing efficiency. But here’s where it gets controversial—Williamson envisions a ‘continuous infrastructure’ alongside the rail route, capable of harnessing wind power and small modular reactors to sustain this mega-city. Is this the future of sustainable urban living, or a logistical nightmare waiting to happen?
In a statement, Williamson admitted, ‘Maybe I’ve been too influenced by the scale and ambition of NEOM’s The Line in Saudi Arabia,’ where he’s worked on high-speed stations. Yet, he argues, ‘We in the British Isles should be equally ambitious.’ Bold words, but they raise a question: Are we ready to shift from cities competing for investment to cities collaborating for a shared future?
This proposal comes on the heels of the UK government’s £45 billion commitment to the Northern Powerhouse Rail (NPR) project, which aims to improve transport, skills, and housing across the north. However, Williamson’s loop city goes far beyond NPR, proposing a Birmingham-Manchester rail line and even a new underground station in Manchester—ideas that have already faced criticism for being too costly. Greater Manchester Mayor Andy Burnham has been vocal about the need for such infrastructure, but rail chiefs remain skeptical. So, who’s right?
And this is the part most people miss: Williamson isn’t the first to dream of a connected northern city. The late Will Alsop proposed a similar linear city 21 years ago, backed by then-Deputy Prime Minister John Prescott. Yet, Williamson’s vision is more ambitious, with estimated construction costs of £130 billion and projected economic benefits of £12 billion annually. Automated vehicles would extend the system’s reach, and the inclusion of Dublin and Belfast could foster unprecedented political cooperation—if border issues can be resolved.
But here’s where it gets controversial: Could this project truly reduce carbon emissions by easing road freight, or is it an environmental gamble? And with the theme of this year’s Royal Academy summer show being ‘interconnectedness,’ Williamson’s proposal couldn’t be timelier. Curators Ryan Gander and Stuart Piercy are sure to spark debate, but the real question is: Can we afford not to think this big?
What do you think? Is Williamson’s loop city a visionary leap forward, or a pie-in-the-sky dream? Let us know in the comments!
